I really appreciate your input. I am looking for a quality product at a reasonable price. I have Dura-Ace on my current bike (an improvement over the Ultegra on the previous one). Most of the input that I have received has been go Campy Record. This is a bike that I hope to ride for years. I think that I am going to go with a Zipp Carbon wheelset (as you recommend). I am leaning toward the Look 595. I think that it is a quality product. Thanks for your honest advice.
